P3D Nvidia VAS Leak Fixed?


Nvidia released a driver update for their GeForce graphics cards, version 378.49 which was reported to leak VAS. They later released another update, version 378.66 which fixed the leak but still had P3D running high VAS usage. The only solution was to roll back to version 376.33 and hope Nvidia fixed the issue.

After being a little annoyed, I actually took it upon myself to simply report this issue to Nvidia using their forums. Prepar3d doesn’t get much, if any, attention in the GeForce forums so it isn’t any surprise the problem existed in two driver builds. After posting the issue with links to the Prepar3d forums I was asked to try the hotfix 378.72 driver to see if the problem was fixed.

I’m happy to say the hotfix driver solved everything and appears to be stable with P3D! In addition, I am actually seeing better VAS results than I was on the 378.66 build. So, if you’d like to update your drivers, go ahead and grab the 378.72 build and see how it goes for you.

    Hey Ryan,

    Could you please share your VAS count at KDCA (by drewitzki design) inside the fslab a320 (P3D) ?

    Tried. No luck for me. Ran into OOM again on my flight from EDDM to LOWW with FSLabs. So I rapidly roll back to 376.33.

    But I noticed slightly more fps 🙂

    Its working very well on 2.5. The ultimate test – FSDT CYVR, CaptainSim777, ORBX PNW and ASN injecting some healthy cloud. Autogen sliders at max and LOD on Ultra, and it actively dumps VAS and keeps it around 3500-3600 MB. Very pleased indeed.

    Nop. Not working. There is a leak somewhere still. It starts around 62% then slowly climbs all the way to 100% in about 1.5 hours for me.

    That is after trying the hotfix driver.

    I found the same here. I tried version (378.78) but still VAS problems. Haven’t been able to complete a flight since. I’m reverting back to 376.33

    Get rid of ORBX VECTOR if you want no more OOMs. Unfortunatelly.
